It will be further appreciated that, for convenience and clarity, spatial terms such as “vertical”, “horizontal”, “up”, and “down” may be used herein with respect to the drawings. However, surgical instruments are used in many orientations and positions, and these terms are not intended to be limiting and/or absolute.

Various exemplary devices and methods are provided for performing laparoscopic and minimally invasive surgical procedures. However, the reader will readily appreciate that the various methods and devices disclosed herein can be used in numerous surgical procedures and applications including, for example, in connection with open surgical procedures. As the present Detailed Description proceeds, the reader will further appreciate that the various instruments disclosed herein can be inserted into a body in any way, such as through a natural orifice, through an incision or puncture hole formed in tissue, etc. The working portions or end effector portions of the instruments can be inserted directly into a patient's body or can be inserted through an access device that has a working channel through which the end effector and elongate shaft of a surgical instrument can be advanced.

A surgical stapling system can comprise a shaft and an end effector extending from the shaft. The end effector comprises a first jaw and a second jaw. The first jaw comprises a staple cartridge. The staple cartridge is insertable into and removable from the first jaw; however, other embodiments are envisioned in which a staple cartridge is not removable from, or at least readily replaceable from, the first jaw. The second jaw comprises an anvil configured to deform staples ejected from the staple cartridge. The second jaw is pivotable relative to the first jaw about a closure axis; however, other embodiments are envisioned in which the first jaw is pivotable relative to the second jaw. The surgical stapling system further comprises an articulation joint configured to permit the end effector to be rotated, or articulated, relative to the shaft. The end effector is rotatable about an articulation axis extending through the articulation joint. Other embodiments are envisioned which do not include an articulation joint.

The staple cartridge comprises a cartridge body. The cartridge body includes a proximal end, a distal end, and a deck extending between the proximal end and the distal end. In use, the staple cartridge is positioned on a first side of the tissue to be stapled and the anvil is positioned on a second side of the tissue. The anvil is moved toward the staple cartridge to compress and clamp the tissue against the deck. Thereafter, staples removably stored in the cartridge body can be deployed into the tissue. The cartridge body includes staple cavities defined therein wherein staples are removably stored in the staple cavities. The staple cavities are arranged in six longitudinal rows. Three rows of staple cavities are positioned on a first side of a longitudinal slot and three rows of staple cavities are positioned on a second side of the longitudinal slot. Other arrangements of staple cavities and staples may be possible.

The staples are supported by staple drivers in the cartridge body. The drivers are movable between a first, or unfired position, and a second, or fired, position to eject the staples from the staple cavities. The drivers are retained in the cartridge body by a retainer which extends around the bottom of the cartridge body and includes resilient members configured to grip the cartridge body and hold the retainer to the cartridge body. The drivers are movable between their unfired positions and their fired positions by a sled. The sled is movable between a proximal position adjacent the proximal end and a distal position adjacent the distal end. The sled comprises a plurality of ramped surfaces configured to slide under the drivers and lift the drivers, and the staples supported thereon, toward the anvil.

Further to the above, the sled is moved distally by a firing member. The firing member is configured to contact the sled and push the sled toward the distal end. The longitudinal slot defined in the cartridge body is configured to receive the firing member. The anvil also includes a slot configured to receive the firing member. The firing member further comprises a first cam which engages the first jaw and a second cam which engages the second jaw. As the firing member is advanced distally, the first cam and the second cam can control the distance, or tissue gap, between the deck of the staple cartridge and the anvil. The firing member also comprises a knife configured to incise the tissue captured intermediate the staple cartridge and the anvil. It is desirable for the knife to be positioned at least partially proximal to the ramped surfaces such that the staples are ejected ahead of the knife.

In at least one instance, the contacts comprises conductor rings configured to permit rotation of the shaft assembly 1200 relative to the handle assembly 1100 about a central longitudinal axis while still permitting electrical transmission between the shaft assembly 1200 and the handle assembly 1100.

The end effector assembly 1300 comprises a first jaw 1310 and a second jaw 1340 movable relative to the first jaw 1310 to grasp and ungrasp tissue therebetween. The first jaw 1310 is fixed relative to the second jaw 1340. In at least one instance, the first jaw 1310 is not fixed and both jaws 1310, 1340 are pivotable relative to each other. The first jaw 1310 comprises a cartridge channel 1320 configured to receive a replaceable staple cartridge assembly 1330 therein. The second jaw 1340 comprises an anvil 1350 configured to clamp onto tissue upon actuation of the closure trigger 1125 and form staples removably stored within the replaceable staple cartridge assembly 1330 upon actuation of the firing trigger 1129. The end effector assembly 1300 further comprises a firing member assembly configured to be actuated through a firing stroke to deploy staples from the replaceable staple cartridge assembly 1330 and cut tissue clamped between the jaws 1310, 1340.

As discussed above, the surgical stapling instrument 1000 may comprise various electronics. Such electronics may be wireless, wired, passively powered, and/or actively powered, for example. Such electronics may be positioned within the staple cartridge assembly 1330, on one or more components of the end effector assembly 1300 such as the cartridge channel jaw 1310 and/or the anvil jaw 1340, within the shaft assembly 1200, and/or within the handle assembly 1100. In at least one instance, electrical leads may be required to traverse the articulation joint 1230. Various arrangements disclosed herein illustrate various ways of passing electrical leads through the articulation joint 1230.

The staple cartridge assembly 1330 further comprises a retainer 1400 installed on the cartridge assembly 1330. In at least one instance, the retainer 1400 is configured to maintain staples within the cartridge assembly 1330 during shipping and/or installation of the cartridge assembly 1330 into the cartridge channel 1320. The retainer 1400 is configured to be removed prior to use of the surgical stapling instrument 1000 and the cartridge assembly 1330.

FIGS. 6-8 illustrate a shaft assembly 2000 configured to be used with a surgical stapling instrument such as those disclosed herein. The shaft assembly 2000 comprises a proximal attachment interface 2010 configured to be attached to and detached from a housing, or handle, assembly, for example. The shaft assembly 2000 accommodates, and passes through, electrical leads, or wires, 2040 through the shaft assembly 2000. The electrical leads 2040 may transmit direct current or any suitable electrical signal, for example, to an end effector assembly. The shaft assembly 2000 comprises an outer shaft 2020, a proximal spine portion, or proximal channel retainer, 2030, and a distal spine portion, or distal channel retainer, 2071. The shaft assembly 2000 comprises an articulation joint 2080. The electrical leads 2040 pass through the shaft assembly 2000 and the articulation joint 2080 within the proximal spine portion 2030. In at least one instance, the leads 2040 are positioned between the outer shaft 2020 and the proximal spine portion 2030. In at least one instance, a dedicated channel is present within the proximal spine portion 2030 through which the leads 2040 pass. In at least one instance, a dedicated channel is present within the inside of the outer shaft, or closure tube, 2020, through which the leads 2040 pass. In at least one instance, the leads are positioned along a longitudinal axis of the shaft assembly 2000. The leads 2040 may be grounded to the proximal spine portion 2030 so as to prevent interference with various other movable components positioned within the shaft assembly 2000.

As can be seen in FIG. 8 , the leads 2040 extend through the articulation joint 2040 and toward an end effector 2070. The leads 2040 enter into the end effector 2070 through a cavity 2072 defined next to the distal spine portion 2071. In at least one instance, additional slack is provided within the leads 2040 to allow the end effector 2070 to be articulated relative to the shaft 2020. In at least one instance, the leads 2040 comprise of a flexible wire constrained at specific locations within the shaft assembly 2000. In at least one instance, the leads 2040 terminate at conductor rings positioned within the proximal attachment interface 2010 which are configured to be electrically coupled to corresponding electrical conductor rings of a handle assembly, for example. Power, and/or data, for example, may be transferred through the conductor rings and through the leads 2040 to the end effector 2070. Sensors, chips, LEDs, and/or any other suitable electronic components positioned within the end effector 2070 may receive electrical signals from the leads 2040. In at least one instance, the leads 2040 are positioned at the bottom of, and center of, the proximal spine portion 2030.

In at least one instance, the leads 2040 comprise redundant leads for redundant supplies of power such as direct power, for example, in the event that one or more of the leads 2040 fail. In such an event, a control circuit is configured to automatically supply power to various electronics of the end effector 2070, for example, through the redundant leads. In at least one instance, the leads 2040 are positioned within the shaft assembly 2040 and grounded to various components which are not configured to move or interact with any other components, for example.

The control circuit may include one, or more, sensors such as, for example, current sensors and/or voltage sensors configured to measure a parameter indicative of a failure of one, or more, leads 2040. For example, the control circuit may detect a short circuit due, for example, to a fluid exposure of the primary leads of the leads 2040. In such instance, the control circuit can be configured to switch a power supply transfer and/or a data signal transfer from the primary leads to redundant leads of the leads 2040.

In at least In at least one example, the control circuit includes a processor and a memory storing program instructions, which when executed by the processor, cause the processor to detect a short circuit in one, or more, primary leads of the leads 2040 based on sensor readings of one, or more, sensors in communication with the processor. The instructions further cause the processor to cause a source of the power and/or the data signal to switch power and/or data signal transmission to one, or more, redundant leads.

FIG. 9 depicts a surgical instrument assembly 2100 comprising a shaft assembly 2110, an articulation joint 2120, and an end effector assembly 2130 articulatable relative to the shaft assembly 2110 by way of the articulation joint 2120. The surgical instrument assembly 2100 further comprises electrical leads 2140 configured to transfer power and/or data signals through the articulation joint 2120. The leads 2140 may be connected to a printed circuit board within the shaft assembly 2110 and/or a handle assembly to which the shaft assembly 2110 is attached. In at least one instance, the leads 2140 are connected to various electrical components positioned within the end effector assembly 2130 such as, for example, sensors onboard a staple cartridge.

The leads 2140 comprise a proximal section 2141 positioned within the shaft assembly 2110, an intermediate section 2142 extending through the articulation joint 2120, and a distal section 2143 positioned within the end effector assembly 2130. The proximal section 2141 is fixed within the shaft assembly 2110 and the distal section 2143 is fixed within the end effector assembly 2130. The intermediate section 2142 comprises a coiled length capable of expanding and contracting to accommodate articulation of the end effector assembly 2130 relative to the shaft assembly 2110. The coiled length can also allow expansion and contraction of the leads 2140 caused by clamping of a jaw of the end effector assembly 2130 where one or more of the leads 2140 may be connected, or attached, to a jaw of the end effector 2130 which translates longitudinally during a clamping motion. For example, various surgical instruments require pulling the end effector assembly proximally into a closure tube, for example, to clamp a jaw. In such an instance, expansion and contraction of the leads 2140 would alleviate such longitudinal translation of the end effector assembly relative to the shaft assembly.

The leads 2140 may comprise any suitable material for a transmission path. In at least one instance, the leads 2140 comprise flexible ribbon cable. For example, the leads 2140 may comprise fiber optic fibers, for example. In at least one instance, the leads 2140 comprise a length capable of permitting a degree of rotation of the end effector assembly 2130 about its longitudinal axis relative to the shaft assembly 2110. In at least one instance, the leads 2140 are configured to transmit direct current to the end effector assembly 2130. In at least one instance, the leads 2140 are sealed in a manner that would prevent tissue and/or fluid, for example, from flowing near and/or around the leads 2140 during a surgical procedure, for example, which may cause electrical components to short out.

In at least one instance, the leads 2140 are fixed to an outer shaft of the shaft assembly 2110 by way of an adhesive, for example. Any suitable attachment mechanism can be used. For example, an electrical terminal may be utilized on both sides of the articulation joint 2120 to which the leads 2140 can connect. Such terminals can act as intermediate points of attachment within the transmission path of the leads 2140 and act only as attachment means for fixing the leads 2140 to various components. In at least one instance, additional leads 2140 are provided and are positioned circumferentially around an outer shaft of the shaft assembly 2110. In at least one instance, the leads 2140 are attached externally to the shaft assembly 2110.

FIGS. 10-16 depict a surgical instrument assembly 3000 comprising a shaft assembly 3100, an articulation joint 3200, and an end effector assembly 3300 configured to be articulated relative to the shaft assembly 3100 about the articulation joint 3200. The surgical instrument assembly 3000 comprises features for passing one or more electrical leads 3420 of an electrical transmission system 3400 through the shaft assembly 3100, the articulation joint 3200, and the end effector assembly 3300. The surgical instrument assembly 3000 may be similar in many respects to the surgical instrument assemblies described in U.S. patent application Ser. No. 12/765,337, entitled SURGICAL STAPLING INSTRUMENT WITH AN ARTICULATABLE END EFFECTOR, now U.S. Pat. No. 8,408,439, which is incorporated by reference herein in its entirety.

The shaft assembly 3100 comprises a proximal spine portion 3110 comprising an articulation pin 3311 (FIG. 13 ) extending from the proximal spine portion 3110 and defining an articulation axis AA. The articulation pin 3211 rotatably couples a distal channel retainer 3330 of the end effector assembly 3300 to the proximal spine portion 3110 such that the end effector assembly 3300 can be articulated relative to the shaft assembly 3100 about the articulation axis AA.

The end effector assembly 3300 comprises a channel jaw 3310 and an anvil jaw 3340, discussed in greater detail below, pivotably coupled to the channel jaw 3310. The end effector assembly 3300 is configured to clamp, unclamp, staple, and cut tissue. In at least one instance, the end effector assembly 3300 comprises a replaceable staple cartridge removably received within the channel jaw 3310. The replaceable staple cartridge may be replaced such that the surgical instrument assembly 3000 can be reused during a surgical procedure. The surgical stapling assembly 3000 comprises a firing member 3150 configured to pass through the shaft assembly 3100, the articulation joint 3200, and the end effector assembly 3300. The firing member 3150 is configured to be linearly actuated such that a firing member assembly attached to a distal end of the firing member 3150 can be linearly translated through the end effector assembly 3300 to staple and cut tissue.

The articulation joint 3200 comprises an articulation support member 3210 configured to support the firing member 3150 within the articulation joint 3200. In at least one instance, the articulation support member 3210 is configured to prevent the firing member 3150 from blowing out during articulation and/or actuation of the firing member 3150 through the end effector assembly 3300 while the surgical instrument assembly 3000 is in an articulated configuration (FIG. 13 ). The articulation support member 3210 comprises a central portion 3211 defining a support slot 3212. The support slot 3212 is configured to receive the firing member 3150 therethrough and support the firing member 3150 through the articulation joint 3200. The articulation support member 3210 further comprises outer pillars 3213 defining slots 3214 between the outer pillars 3213 and the central portion 3211. In at least one instance, the slots 3214 are configured to receive one or more articulation actuation members therethrough, discussed in greater detail below. The articulation support member 3210 is configured to move within the articulation joint 3200 as the end effector assembly 3300 is articulated about the articulation axis AA and support the firing member 3150 during articulation of the end effector assembly 3300. In at least one instance, the firing member 3150 comprises a plurality of bands laterally positioned with respect to one another which are configured to splay during articulation of the end effector assembly 3300.

The distal channel retainer 3330 is fixedly attached to the channel jaw 3310 such that, as articulation forces are applied to the distal channel retainer 3330, the end effector assembly 3300, as a whole, is articulated about the articulation axis AA. The distal channel retainer 3330 comprises an actuation post 3331 distal of the articulation axis AA configured to receive the articulation forces. In at least one instance, an articulation band, rod, and/or actuator, is configured to push and pull the post 3331 to apply a torque to the end effector assembly 3300 and cause the end effector assembly 3300 to articulate about the articulation axis AA. The articulation actuator may pass through one of the slots 3214 defined in the articulation support member 3210.

The distal channel retainer 3330 comprises a proximal portion 3255 which receives the articulation pin 3311. The proximal portion 3255 further comprises locking teeth 3256 formed thereon. The surgical instrument assembly 3000 further comprises an articulation locking system 3250 comprises an articulation lock bar 3252 and a proximal articulation lock actuator 3251 configured to push and pull the articulation lock bar 3252. The articulation lock bar 3252 comprises a distal locking head 3253 configured to engage and disengage the locking teeth 2356. The articulation lock bar 3252 may be actuated longitudinally by any suitable source. For example, the articulation lock bar 3252 may be actuated manually by a clinician, automatically by a surgical robot, and/or automatically by way of a passive locking system where the lock bar 3252 locks the articulation joint 3200 anytime the end effector assembly 3300 is not being articulated. For example, the articulation lock bar 3252 may be spring loaded distally so that the lock bar 3252 remains engaged with locking teeth 3256 until articulation control motions, or forces, are applied to the end effector assembly 3300 to articulate the end effector assembly 3300 about the articulation axis AA. Once a desired articulated position is achieved and/or articulation control motions are not being applied to the end effector assembly 3300, the lock bar 3252 may re-engage the locking teeth 3256 and hold the end effector assembly 3300 in its articulation position until further articulation control motions are applied to the end effector assembly 3300, for example. In at least one instance, the articulation lock bar 3252 is actuated by a solenoid, for example. In at least one instance, the lock bar 3252 is advanced distally with a closure tube configured to clamp tissue. Such an arrangement can aid in preventing articulation of the end effector assembly 3300 owing to bumping the end effector assembly 3300 inside of a patient, for example. Such an arrangement can also prevent straightening of the surgical instrument assembly 3000 owing to blowout forces applied to the articulation joint 3200 by the firing member 3150 during actuation of the firing member 3150 and/or during articulation of the end effector assembly 3300, for example.

In various instances, the articulation joints disclosed herein comprise an articulation joint cover. As discussed the articulation joint cover can comprise one or more electrical leads and/or braided wire structures. In at least one instance, the articulation joint cover comprises an electrically activatable solenoid coil. In such an instance, the coil can be energized to actuate the lock bar 3252. In at least one instance, a solenoid structure is provided proximal to the articulation joint and is positioned within the shaft assembly and/or surgical instrument handle and/or robot, for example. The lock bar 3252 may be actuated at any suitable time. For example, the lock bar 3252 may be automatically and/or manually actuated into a locked position when an anvil jaw is in a partially and/or fully clamped position.

The distal channel retainer 3330 further comprises a distal support structure, or pillar, 3320 comprising a firing member slot 3321 defined therein. In at least one instance, the distal support structure 3320 is attached to the channel jaw 3310, for example. The firing member slot 3321 is configured to receive the firing member 3150 therethrough permitting the firing member 3150 to pass through and into the channel jaw 3310 and the anvil jaw 3340.

As discussed above, the surgical instrument assembly 3000 comprises one or more electrical leads 3420 configured to pass through the shaft assembly 3100, the articulation joint 3200, and the end effector assembly 3300. The electrical leads 3420 may be used for any of the purposes described herein. For example, the electrical leads 3420 may transmit electrical signals between a surgical robot and sensors positioned within the end effector assembly 3300, for example. Such signals may comprise power and/or data information, for example.

Referring to FIGS. 14-16 , the electrical transmission system 3400 comprises a proximal spool 3410 mounted within the shaft assembly 3100 proximal of the articulation joint 3200, electrical leads 3420 attached to the proximal spool 3410 and extending through the shaft assembly 3100, the articulation joint 3200, and the end effector assembly 3300, and a termination assembly 3430 positioned within the end effector assembly 3300 where the electrical leads 3420 are configured to terminate.

The proximal spool 3410 is mounted within the shaft assembly 3100 and is configured to feed wire as the end effector assembly 3300 moves through its articulated and non-articulated configurations. The spool 3410 may be electrically coupled to electrical leads proximal of the spool 3410 configured to transmit electrical signals back to a surgical instrument handle and/or surgical robot, for example. The electrical leads 3420 may float within the surgical instrument assembly 3000 such that the spool 3410 can provide more wire as the end effector assembly 3300 is articulated into a fully articulated position and absorb excess wire as the end effector assembly 3300 is articulated back into a non-articulated position. As the end effector assembly 3300 is articulated, more wire may be fed by the spool 3410 to accommodate the extra travel distance required by articulation of the end effector assembly 3300. As the end effector assembly 3300 is articulated back into a non-articulated position, the wire fed by the spool 3410 may be spooled back around the spool 3410. In at least one instance, clamping and unclamping of the anvil jaw 3430 may also require additional wire to be fed from the spool 3410.

In at least one instance, such winding and unwinding of the leads 3420 may be assisted by a spring, for example. In at least one instance, the spool 3410 is spring loaded such that the end effector assembly 3300 may be able to overcome the spring force of the spool 3410 as the end effector assembly 3300 is articulated to pull and unwind additional wire from the spool 3410. Similarly, the spring force of the spool 3410 is configured to rewind the excess wire just provided when the end effector assembly 3300 is articulated back into a non-articulated position.

In at least one instance, such winding and unwinding of the leads 3420 may be assisted by a motor, for example. Actuation of the spool motor may be configured to coincide with the articulation control motions, for example.

The electrical leads 3420 extend from the spool 3410 and through the articulation joint 3200. Specifically, the electrical leads 3420 extend through one of the slots 3214 of the articulation support member 3210. The support structure 3320 further comprises a channel 3322 defined therein configured to receive the electrical leads 3420 therethrough. The channel 3322 comprises an arcuate profile. In at least one instance, the electrical leads 3420 comprise a flexible circuit cable. In such an instance, the flexible circuit cable defines a cable plane corresponding to a profile of the channel 3322. In at least one instance, the electrical leads 3420 are attached to sidewalls of the channel 3322. In at least one instance, the channel 3322 comprises an open top portion. In at least one instance, the channel 3322 comprises a tunnel-like profile such that the leads 3420 are fed through the one side of the channel 3322 and out the other side of the channel 3322. The channel 3322 is configured to pass the leads 3420 therethrough on an opposite side of the longitudinal axis LA where the actuation post 3331 is positioned. In at least one instance, the channel 3322 and the actuation post 3331 are positioned on the same side of the longitudinal axis LA.

As can be seen in FIGS. 15 and 16 , the leads 3420 are further configured to pass through the anvil jaw 3340 and terminate at the termination assembly 3430. The anvil jaw 3340 comprises a proximal end 3341 comprising proximally-extending arms 3342 each comprising an anvil trunnion 3343 extending therefrom. The anvil trunnions 3343 are configured to be received within a corresponding anvil trunnion slot defined in the channel jaw 3310. The anvil jaw 3340 further comprises a proximal aperture 3345 defined therein configured to receive a top camming portion of a firing member assembly therein such that the top camming portion of the firing member assembly may be positioned within a longitudinal camming channel 3346 defined in the anvil jaw 3340. The anvil jaw 3340 further comprises a channel 3347 defined in one of the arms 3342 configured to receive the electrical leads 3420 therethrough.

The termination assembly 3430 may comprise electrical contacts, for example, and may be attached to the anvil jaw 3340 and/or the channel jaw 3310. In at least one instance, the termination assembly 3430 is in electrical communication with the replaceable staple cartridge. In at least one instance, each replaceable staple cartridge installed within the end effector assembly 3300 may comprise sensors, for example, which require electrical transmission between the termination assembly 3430 and corresponding contacts, for example, on the replaceable staple cartridge.

The channel 3347 is positioned such that the leads 3420 are not interfered with during and/or after assembly of the end effector assembly 3300. In at least one instance, a firing member assembly with a cutting knife, for example, and the anvil jaw 3340 are assembled prior to installing the leads 3420. The leads 3420 are positioned laterally away from a firing slot 3344 and vertically away from a top camming portion of the firing member assembly. Such a configuration can prevent inadvertent damage to the leads 3420 during and/or after assembly of the leads 3420 and the end effector assembly 3300. As can be seen in FIG. 16 , the channel 3347 provides positioning of the electrical leads 3420 vertically away from the channel 3346 to prevent interference between the firing member 3150, the firing member assembly, and the electrical leads 3420, for example.

In various instances, electrical transmission is required between a shaft assembly and a surgical handle assembly and/or surgical robot for example where the shaft assembly is rotatable relative to the interface to which it is attached. For example, the shaft assembly 1200 illustrated in FIG. 1 is configured to rotate relative to the handle assembly 1100 in order to better position the end effector assembly 1300 for clamping, stapling, and cutting tissue. FIG. 17 depicts a surgical instrument assembly 3500 comprising an outer nozzle 3510, an inner shaft frame assembly 3520, and electrical leads 3530 configured to transmit electrical signals between the nozzle 3510 and the inner shaft frame assembly 3520. The nozzle 3510 is configured to be rotated relative to the inner shaft frame assembly 3520 to rotate a shaft and/or end effector assembly connected to the nozzle 3510. The inner shaft frame assembly 3520 may extend from a handle assembly and be stationary relative to the nozzle 3510.

The surgical instrument assembly 3500 further comprises a shaft-rotation limiting system configured to prevent over rotation of the nozzle 3510 relative to the shaft assembly 3520. Preventing over rotation of the nozzle 3510 relative to the shaft frame assembly 3520 can prevent stretching, tearing, or damage of the electrical leads 3530. The nozzle 3512 comprises a tab 3512 extending from an inner annular surface 3511 of the nozzle 3510. The shaft frame assembly 3520 comprises a tab 3522 extending from an outer annular surface 3521 of the shaft frame assembly 3520. As the nozzle 3510 is rotated relative to the shaft frame assembly 3520, the tabs 3512, 3522 are configured to abut each other and prevent further rotation of the nozzle 3510 in a specific direction. In at least one instance, the surgical instrument assembly 3500 comprises a control circuit configured to electronically limit the degree of relative rotation between the nozzle 3510 and the shaft assembly 3520. In at least one instance, current is monitored of a motor configured to rotate the nozzle 3510, for example, and, when a current spike is detected, over rotation of the nozzle 3510 is determined owing to the engagement of the tabs 3512, 3522.

FIG. 18 depicts a ring assembly 3600 configured to be employed in a surgical instrument assembly such as those described herein. The ring assembly 3600 comprises a plurality of rings 3610, 3612, 3614 configured to transfer rotational control motions to each other and a hard stop 3620 configured to prevent a specific degree of rotation of the rings 3610, 3612, 3614 beyond a certain configuration. The ring assembly 3600 permits multiple full revolutions of a shaft rotational mechanism, for example, while still providing a hard stop. For example, a shaft to be rotated may be connected to the ring 3614. The ring 3614 can be rotated in a clockwise direction and, after a full revolution, a tab 3615 extending from the ring 3614 is configured to engage a tab 3613 of the ring 3612. The shaft may be continue to be rotated clockwise another full revolution where, after a full revolution of the ring 3612, the tab 3613 engages a tab 3611 of the ring 3610. The shaft may continue to be rotated clockwise a final full revolution where, after a fully revolution of the ring 3610, the tab 3611 engages the hard stop 3620. Such a configuration can provide a physical hard stop while still providing multiple full revolutions of a shaft assembly. Electrical leads may be wrapped, or coiled, around a shaft assembly which permit multiple revolutions of a shaft assembly. The rings 3610, 3612, and 3614 are configured to stack rotational motion of a shaft assembly, for example.

While the rotation-limiting features of the ring assembly 3600 are illustrated in the form of tabs, other forms are contemplated by the present disclosure including any suitable interlocking members. In other instances, the ring thicknesses can be adjusted to prevent rotation beyond a threshold via friction between rings of a ring assembly, for example.

The assemblies provided in FIGS. 17 and 18 may prevent infinite rotation of a component relative to another component where electrical leads that transfer electrical signals between the components are provided. In various instances, limiting tabs or stacks of limiting tabs are provided throughout surgical instrument assemblies at a variety of locations. For example, such arrangements can be provided within an end effector assembly, a shaft assembly, an attachment interface configured to be attached to a surgical robot, and/or a surgical instrument handle assembly, for example. Such limiting tabs or stacks of limiting tabs may prevent a specific degree of rotation of any suitable rotary drive mechanism, for example. In at least one instance, limit tabs comprise electrical stop switches configured to signal to a motor and/or a user, for example, that a rotational limit has been reached. The tabs may close/open the switches accordingly. In such an instance, a control circuit may stop the corresponding motor, for example, rotating the shaft assembly and/or alert a user of the over rotation. In at least one instance, the tabs are configured to close an electrical circuit and indicate to a user that the rotational limit has been reached. In such an instance, the tabs may comprise a conductive material configured to close a rotational limit circuit. In at least one instance, a rotational limit circuit may be employed with stacks of tabs such as those described above. In such an instance, a control circuit can indicate to a user how many revolutions a shaft assembly has been rotated and, when a predetermined number of rotations has been reached, alert a user that the rotational limit is being approached and, in at least one instance, place the motor providing the shaft rotation in a limp mode in an effort to prevent an abrupt rotational stop.

The control circuit may include a processor and a storage medium, e.g. a memory, storing program instructions that, when executed by the processor, causes the processor to determine a number of revolutions a shaft assembly has been rotated and, cause a user interface, e.g. a display, to inform a user of the number of revolutions, and/or place the motor providing the shaft rotation in a limp mode in an effort to prevent an abrupt rotational stop. In instances, where the ring assembly 3600 comprises conductive tabs that close a circuit upon contact with one another, the processor may determine that the predetermined number of revolutions has been reached based on a change in the circuit status from open to closed.

The electrical leads 3822 are configured to accommodate the stretching of the articulation joint cover 3810 owing to articulation of an end effector assembly relative to a shaft to which the joint cover 3810 is attached. The electrical leads 3822 comprise an intermediate relief section 3821 providing additional length, or slack, to the electrical leads 3822 to provide stretching relief to the electrical leads 3822. Such an arrangement can prevent strain and/or damage of the electrical leads 3822 during end effector articulation.

In various instances, surgical end effectors comprise sensors and/or other electronic components which can require various electrical signals to be passed to and from such sensors and components. Electrical signals, such as power and/or data signals, digital and/or analog, for example, may be required to be passed or transferred between the sensors and/or electronic components within an end effector and a handle and/or a surgical robot through an attachment interface, for example. In such instances, a plurality of electrical leads can be utilized between the surgical end effector and the handle, for example, to transfer electrical signals therebetween. In various instances, the end effector comprises an articulation joint. Articulation joints may add additional architecture within a shaft assembly where space may be limited. For example, articulation joints may require an articulation drive train. Such an articulation drive train, in addition to other drive trains and components housed within the shaft assembly, can consume valuable space within such shaft assemblies. In various instances, surgical end effectors may require a plurality of individual electrical leads for each sensor and/or electronic component onboard the surgical end effector. Various arrangements for minimizing the amount of electrical leads passing through a shaft assembly, articulation joint, and end effector are disclosed.

In such an instance, the articulation rod 5120 pulls the proximal section 5411 distally and bunches up, or bends, the intermediate section 5412 to provide the necessary slack in the electrical lead 5410 for the subsequent articulated position. Articulating the end effector assembly 5300 in a direction opposite to the direction 5201 will cause the articulation rod 5120 to at least partially reduce the amount of slack in the electrical lead 5410 where, when the end effector assembly 5300 is articulated in this direction, less distance of cable is required of the electrical lead 5410.

FIG. 28 depicts an articulation assembly 5500 for use with a surgical instrument assembly such as those described herein.

FIG. 33 illustrates the cable 6410 in a partially un-winded configuration. Should the distal lead portion 6414 be articulated in a direction opposite to the direction illustrated in FIG. 33 , the coiled portion 6413 would wind in an opposite direction. In at least one instance, the coiled portion 6413 winds tighter when the end effector assembly 6300 is articulated in a first direction and unwinds looser when the end effector assembly 6300 is articulated in a second direction opposite the first direction. Such a configuration may provide relief within a flexible cable 6410 which extends through an articulation joint 6200. Such a configuration provides a length of cable 6410 which is coiled, and/or rolled, for example, within the articulation joint 6200 centered around the articulation axis AA. In at least one instance, the coiled section 6413 is not centered around the articulation axis AA.

While the electrical system 6400 illustrates a cable configured to accommodate articulation, such a configuration can also be used for end effector rotation about a longitudinal axis relative to a shaft assembly. In at least one instance, a flexible cable is provided which can wind and un-wind in multiple planes to accommodate both end effector articulation as well as end effector rotation. Such a cable configuration can prevent tearing of a flexible PCB, for example, which extends through an articulation joint. In at least one instance, such a cable can be employed through multiple distinct articulation joints each having its own articulation axis.

In various instances, surgical staple cartridges, replaceable or not replaceable, comprise electronic components. Such electronic components may comprise active components, passive components, and/or electromechanical components. For example, such components may comprise conductive components, integrated circuits, programmable devices, display technologies, power sources, resistive components, capacitive components, magnetic devices, and/or switches, for example. One or more of such components may require that the staple cartridge be electrically coupled with a cartridge channel jaw, for example, so as to transmit electrical signals between the staple cartridge and a surgical instrument handle and/or surgical robot, for example. The electrical signals may be digital and/or analog. The electrical signals may comprise data signals and/or power signals, for example. In at least one instance, the electrical signals comprise data corresponding to cartridge type, cartridge length, and/or staple length, for example.

FIGS. 34-36 depict a surgical end effector 7000 comprising a cartridge channel jaw 7100 and an anvil jaw 7200 pivotable relative to the cartridge channel jaw 7100. The end effector 7000 further comprises a replaceable staple cartridge 7130 removably positioned within a cartridge channel 7110 of the cartridge channel jaw 7100. The staple cartridge 7130 may comprise one or more electronic components such as those disclosed herein. The staple cartridge 7130 further comprises a sled 7131 movable through a firing stroke between a proximal, unfired position and a distal, fully fired position. The sled 7131 is configured to eject staples from the staple cartridge 7130 and is configured to be pushed distally by a longitudinally-translatable firing member. The end effector 7000 further comprises a lockout member 7120 configured to prevent the firing member from being advanced distally through the staple cartridge 7130 until a lockout condition is overcome.

In at least one instance, the lockout member 7120 is overcome, or unlocked, by the installation of an unfired, proper staple cartridge. The lockout member 7120 is further configured to electrically couple the staple cartridge 7130 with an electrical lead extending proximally from the lockout member 7120. The electrical lead may be in electrical communication with a control circuit of a surgical robot and/or a surgical instrument handle, for example. The staple cartridge 7130 further comprises a conductive member 7132 extending proximally from the staple cartridge 7130. In at least one instance, the conductive member 7132 comprises one or more conductive leads printed thereon. In at least one instance, the conductive member 7132 itself comprises an electrical pathway. In at least one instance, the conductive member 7132 is electrically coupled with one or more electrical components of the staple cartridge 7130 such as those described herein. The conductive member 7132 is configured to contact a distal end 7121 of the lockout member 7120 to electrically couple the staple cartridge 7130 with a surgical instrument handle and/or surgical robot, for example.

The lockout member 7120 further comprises corresponding conductive traces 7122 printed thereon. In at least one instance, the traces 7122 are printed on the lockout member 7120 after the lockout member 7120 is stamped and/or machined. The traces 7122 extend the entire length of the lockout member 7120 and are configured to contact the conductive member 7132 to electrically couple the staple cartridge 7130 to the electrical lead extending to the surgical robot and/or surgical instrument handle, for example. In at least one instance, the lockout member 7120 is only electrically coupled with the staple cartridge when the lockout member 7120 is in an unlocked position. In at least one instance, the lockout member 7120 is electrically coupled with the staple cartridge 7130 regardless of the position, or condition, of the lockout member 7120. See U.S. patent application Ser. No. 14/314,108, entitled METHOD OF USING LOCKOUT FEATURES FOR SURGICAL STAPLER CARTRIDGE, now U.S. Pat. No. 10,335,147, for example, which is incorporated by reference in its entirety.

In at least one instance, the lockout member 7120 comprises a lockout spring member. In at least one instance, the conductive member 7132 extends proximally from the sled 7131. In such an instance, terminals are provided between the cartridge 7130 and the sled 7131 to electrically couple electronic components positioned within the staple cartridge with the sled 7131, the conductive member 7132, the lockout member 7120, and the surgical instrument handle and/or surgical robot.

In various instances, surgical instrument assemblies provided herein are configured to identify a type of staple cartridge which is installed in a cartridge channel without any corresponding electronic components within the staple cartridge and/or end effector assembly. Such an arrangement can reduce the amount of electrical wiring passing through various components of a surgical instrument assembly, for example.

Referring to FIGS. 37-39 , a staple cartridge assembly 7200 is depicted comprising features for cartridge identification without the need for electrical components onboard the staple cartridge assembly 7200. The staple cartridge assembly 7200 may be similar in many respects to other staple cartridges disclosed herein. The staple cartridge assembly 7200 can be used with any suitable surgical instrument assemblies such as those described herein. The staple cartridge assembly 7200 comprises a cartridge body 7210, a sled 7220 movable between a proximal, unfired position (FIG. 38 ) and a distal, fully-fired position to deploy staples from the cartridge body 7210, and a cartridge pan 7230 configured to hold the sled 7220, staples, and/or staple drivers within the cartridge body 7210. The cartridge body 7210 comprises a cartridge deck 7211, a plurality of longitudinal rows of staple cavities 7212 defined in the cartridge deck 7211, and a longitudinal slot 7214 bifurcating the cartridge body 7210. The longitudinal slot 7214 is configured to receive at least a portion of the sled 7220 during a staple firing stroke and a firing member configured to push the sled 7220 through the staple firing stroke.

The cartridge body 7210 further comprises a proximal end 7213 comprising an identification features 7216 defined in a proximal end 7215 of the longitudinal slot 7214. The features 7216 are configured to be engaged by the sled 7220 and/or firing member prior to the staple firing stroke. The features 7216 are detectable by a control circuit of a surgical instrument handle and/or surgical robot and are configured to correspond to one or more identification parameters of the staple cartridge assembly 7200 such that, upon detecting the features 7216, specific identification parameters of the staple cartridge assembly 7200 can be interpolated based on the detected information of the features 7216, discussed in greater detail below.

The features 7216 comprise bosses, or ridges, 7217 and extend for a specific length within the proximal end 7215 of the slot 7214. The ridges 7217 are positioned such that the sled 7220 and/or firing member engage the ridges 7217 prior to the staple firing stroke during an initial pre-firing stroke. The ridges 7217 can interrupt movement of the sled 7230 and/or firing member. In at least one instance, motor current of the motor which actuates the firing member is monitored and through such monitoring, the ridges 7217 are detectable. In at least one instance, the ridges 7217 require greater motor current, for example, to traverse which can be detected and identified. In such an instance, the amount of increased current may correspond to one or more specific cartridge parameters. In at least one instance, the ridges 7217 simply create a recognizable motor current pattern. In such an instance, the pattern detected corresponds to one or more specific cartridge parameters. The cartridge parameters and corresponding detectable feature or patterns (of current, for example) may be stored in a look up table, or database, for example, in a storage medium such as, for example, a memory unit. A control circuit is configured to compare the detected feature and/or pattern, for example, to the information in the lookup table to identify the type of cartridge installed within the end effector assembly.

The sled 7220 comprises a distal portion 7221 comprising a first width and a proximal portion 7222 comprising a second width. The second width may be configured such that the proximal portion 7222 engages the features 7216 as the proximal portion 7222 passes the features 7216; however, after passing the features 7216, the proximal portion 7222 does not interfere with the rest of the slot 7214. While engagement of the sled 7220 and features 7216 is illustrated, the features 7216 may be engaged by the firing member in addition to, or in lieu of, the sled 7220. In at least one instance, current of the motor which drives the firing member and/or sled is monitored. In at least one instance, velocity of the firing member and/or sled is monitored. In at least one instance, vibration of the firing member and/or sled is monitored.

FIG. 39 is a graph 7240 of one scenario where motor current is monitored as a firing member is advanced through the staple cartridge assembly 7200. In at least one instance, the force required to advance the firing member through the staple cartridge assembly 7200 is interpolated from the monitored motor current. As can be seen in the graph 7240, a recognizable force pattern is detected during the initial pre-firing stroke. As discussed above, the force pattern is an identifiable unique profile of the specific staple cartridge assembly 7200. In at least one instance, other cartridges comprising cartridge parameters different from the staple cartridge assembly 7200 comprise different unique ridges which produce different corresponding unique force profiles. Variations of the ridges 7216 may include for example, ridge depth, ridge profile, and/or ridge quantity, for example. One or more of such variations may be employed to produce unique, detectable cartridge identification features 7216 for each possible type of staple cartridge.

In at least one instance, actuation of the firing member during the initial pre-firing stroke is constant between all different types of staple cartridges and only after the type of staple cartridge is identified is an actuation profile determined and employed to advance the firing member through a staple firing stroke. Once the type of cartridge is identified, a range of operational parameters of the surgical instrument assembly may be selected for the identified cartridge. Firing stroke duration, force, and/or speed, for example, may be selected based on the type of cartridge identified. In at least one instance, a user is alerted of the type of cartridge identified and the user selects various operational parameters for the staple firing stroke. As can be seen from the graph A33, the force profile detected through the features 7216 is less than the force profile of the firing stroke where tissue is transected and staples are deployed and formed. In at least one instance, the force profile detected through the features 7216 is greater than the force profile of the firing stroke.

In at least one instance, the features 7216 are similar to that of a braille code. In at least one instance, identifiable cartridge parameters include cartridge color, type, length, date of cartridge manufacture, and/or cartridge lot number, for example. In at least one instance, the features 7216 comprise a firing-force feedback code. In at least one instance, the features 7216 are positioned within a no-cartridge lockout zone where the firing member is also configured to defeat a first stage of a lockout. Such a first stage includes locking a firing member if a cartridge is not installed within an end effector assembly. Such cartridge identification information may be logged for each staple cartridge installed and/or used with a surgical instrument handle/or robot, for example.

FIG. 40 depicts an electrical lead cable 7300 comprising electrical leads 7310. The electrical lead cable 7300 may be used with any surgical instrument assembly such as those disclosed herein. The electrical lead cable 7300 is configured to extend through a shaft assembly, an articulation joint, and an end effector assembly. The electrical lead cable 7300 is configured to expand and contract owing to articulation of an end effector assembly, for example. The electrical lead cable 7300 comprises a plurality of vertical support members 7320 and horizontal support members 7330. The pattern of support members 7320, 7330 can provide a structure that can expand, stretch, contract, and/or compress. The electrical lead cable 7300 can act similar to that of a natural spring. The support members 7320, 7330 may comprise of any suitable material. In at least one instance, the support members 7320, 7330 comprise an elastic material. The electrical leads 7310 may be coiled, or woven, around the horizontal support members 7320, 7330, for example. In at least one instance, the electrical lead cable 7300 comprises multiple layers of material adhered together and the electrical leads 7310 and/or support members 7320, 7330 are positioned between the adhered layers.

In various instances, braided sleeve members can be employed with electrical leads to pass electrical signals between a shaft assembly, an articulation joint, and/or an end effector assembly. FIG. 41 depicts an articulation joint cover 7400 comprising a braided sleeve 7410 configured to be crimped to a distal end of a shaft assembly and a proximal end of an end effector with crimp rings 7420. The joint cover 7400 may be similar in many respects to other articulation joint covers disclosed herein. The braided sleeve 7410 comprises electrical leads 7413 and 7411. The electrical leads 7411, 7413 may comprise printed flex circuit cable, for example. In at least one instance, the electrical leads 7411, 7413 comprises conductive wires, for example. In at least one instance, the electrical leads 7411, 7413 comprise a combination of conductive wires and printed flex circuit cable.

In at least one instance, the electrical leads 7411, 7413 are positioned between insulative layers of material. In such an instance, one insulative layer may comprise an inner insulative layer and be positioned directly adjacent components of the articulation joint and a second insulative may comprise an outer insulative layer and be the outer most layer of the articulation joint component 7400. In at least one instance, such a braided sleeve of electrical leads is employed around at least a length of a shaft assembly and/or an end effector assembly. The braided sleeve configuration can be configured such that the length of sleeve 7410 permits a degree of flexion and contraction during articulation of an end effector assembly, for example. In at least one instance, the leads 7411, 7413 are woven along the length of the sleeve 7400. In at least one instance, the leads 7411 comprise an outer layer of leads and the leads 7413 comprise an inner layer of leads 7413. A braided sleeve may reduce the need for electrical leads passing through an articulation joint near mechanically-integrated components within the articulation joint where risk of pinching and/or tearing is greater than outside of the articulation joint. In at least one instance, such a braided sleeve can also act to protect components of an articulation joint. In at least one instance, electrical leads such as those disclosed herein comprise cables and/or wires and may be flat and/or round for example. In at least one instance, the crimp rings 7420 comprise an insulative material. In at least one instance, a flexible circuit cable comprising one or more electrical leads acts as an articulation joint cover by itself. In such an instance, a nonconductive portion of the flexible circuit cable may protect the components of an articulation joint, for example.

FIG. 42 depicts a shaft assembly 7500 comprising a shaft 7510, electrical leads 7520, 7540 wrapped around the shaft 7510, and an insulative layer 7560 covering the leads 7520, 7540. The leads 7520, 7540 are attached to each other and/or the shaft 7510 by way of connection points 7530, 7550. In at least one instance, the connection points 7530, 7550 comprise hook and loop engagements, for example, between the leads 7520, 7540 and/or between the leads 7520, 7530 and the shaft 7510. Such connection points may limit excessive movement of the electrical leads 7520, 7540 rotationally or longitudinally relative to each other and/or the shaft 7510. In at least one instance, the leads 7520, 7540 comprise a woven sleeve arrangement which weaves the leads 7520, 7540 around the shaft 7510. In at least one instance, the leads 7520, 7540 comprise flexible printed circuit cables.

FIG. 43 depict an articulation joint cover 7600 comprising an electrical lead 7610 coiled around an articulation joint between a proximal end 7601 and a distal end 7603. The articulation joint cover 7600 further comprises connection points 7620. In at least one instance, the connection points 7620 comprise hook and loop arrangements. The connection points 7620 are configured to attach the lead 7610 to one or more components of an articulation joint such as, for example, coupler portions which couple a shaft assembly and an end effector assembly. In at least one instance, the connection points 7620 control the amount of relative movement between the components to which the lead 7610 is fixed and the lead 7610 itself. Too much relative movement may cause the lead 7610 to get pinched, for example, within the articulation joint if no connections are present to slightly restrict targeted movement of the lead 7610.

In various instances, expansion and contraction of electrical leads places such leads under a degree of stress. FIGS. 44 and 45 depict a surgical instrument assembly 7700 comprising a shaft assembly 7710, an articulation joint 7720, and an end effector assembly 7730. The end effector assembly 7730 is articulatable relative to the shaft assembly 7710 by way of the articulation joint 7720. The surgical instrument assembly 7700 further comprises an electrical system 7740 configured to pass electrical signals between the shaft assembly 7710 and the end effector assembly 7730 across the articulation joint 7720. The electrical system 7740 comprises a proximal electrical lead 7741 extending through the shaft assembly 7710 toward a distal end of the shaft assembly 7110. The proximal electrical lead 7741 terminates at a conductive pin, or post, 7743 positioned at the distal end of the shaft assembly 7710.

The electrical system 7740 further comprises two conductive members 7745 extending through the articulation joint and an end effector lead 7747 extending from the two conductive members 7745 and distally into the end effector assembly 7730. The conductive members 7745 are configured to pass electrical signals across the articulation joint 7720. The conductive members 7745 are redundant electrical pathways such that, depending on the articulated position of the end effector assembly 7730, the conductive members 7745 are each configured to electrically couple the end effector lead 7747 to the proximal lead 7741. As can be seen in FIG. 45 , one of the conductive members 7745 is pressed against the conductive pin 7742. In such an instance, that particular conductive member 7745 electrically couples the end effector lead 7747 to the proximal lead 7741. When the end effector assembly 7730 is articulated in the opposite direction, the other conductive member 7745 electrically couples the end effector lead 7747 to the proximal lead 7741. In at least one instance, one of the conductive members 7745 is always in contact with the conductive pin 7743 such that electrical transmission between the proximal lead 7741 and the end effector lead 7747 is always maintained. As can be seen in FIG. 44 , both conductive members 7745 are in contact with the pin 7743 when the end effector assembly 7730 is in a non-articulated, or straight, configuration. In at least one instance, the conductive members 7745 comprise leaf spring members.

FIG. 46 depicts a staple cartridge assembly 8000 comprising a cartridge body 8010 comprising a proximal end 8011, a cartridge pan 8020, and a pressure sensor matrix 8030 comprising a plurality of pressure points 8031 disposed on the cartridge body 8010. In at least one instance, the pressure points 8031 are positioned on an anvil and/or cartridge channel. In at least one instance, the pressure points 8031 comprise a unique profile such that, when pressed against a corresponding pressure sensor matrix comprising a plurality of pressure sensors, such as a surface of an anvil, for example, a control circuit can identify a unique pressure point profile on the cartridge body 8010. The unique pressure point profile is configured to press corresponding pressure sensors to communicate the unique profile to the control circuit. The unique pressure point profile is unique to the staple cartridge assembly 8000 such that one or more specific cartridge parameters can be determined through the pressure sensor matrix and pressure point matrix. The pressure points 8031 may comprise raised portions of the cartridge body 8010. In at least one instance, pressure points are employed on the bottom of the cartridge body 8010 or pan 8020.

FIG. 47 depicts a pan 8100 comprising a pressure point matrix 8120 configured to contact a corresponding pressure sensor matrix. The pressure point matrix 8120 comprises raised pressure points 8121 and non-raised locations 8122. The unique pressure point matrix 8120 is specific to a cartridge to which the pan 8100 is attached. In at least one instance, the pressure point matrix 8120 is engaged upon installation of a staple cartridge assembly into a cartridge channel. In such an instance, the cartridge channel comprises the corresponding pressure sensor matrix configured to read the pressure point matrix and identify the type of staple cartridge assembly being installed within the cartridge channel. In at least one instance, one or more of the pressure points is sheared off by a camming member of a firing member, for example, and, in such an instance, the only information change provided with the new pressure point matrix can include the cartridge has already been used.

With a four-point pressure point matrix 8200 (FIG. 48 ), a total of sixteen different patterns and, thus, types of cartridges, can be employed and identified. More or fewer pressure point locations can be employed to increase the amount of iterations possible for identification. FIG. 49 depicts the sixteen 8300 possible pressure point iterations 8301 with a four-point pressure point matrix.

As used in any aspect herein, the terms “component,” “system,” “module” and the like can refer to a computer-related entity, either hardware, a combination of hardware and software, software, or software in execution.

As used in any aspect herein, an “algorithm” refers to a self-consistent sequence of steps leading to a desired result, where a “step” refers to a manipulation of physical quantities and/or logic states which may, though need not necessarily, take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It is common usage to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. These and similar terms may be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities and/or states.

A network may include a packet switched network. The communication devices may be capable of communicating with each other using a selected packet switched network communications protocol. One example communications protocol may include an Ethernet communications protocol which may be capable permitting communication using a Transmission Control Protocol/Internet Protocol (TCP/IP). The Ethernet protocol may comply or be compatible with the Ethernet standard published by the Institute of Electrical and Electronics Engineers (IEEE) titled “IEEE 802.3 Standard”, published in December, 2008 and/or later versions of this standard.

Of course, different and/or after-developed connection-oriented network communication protocols are equally contemplated herein.

Unless specifically stated otherwise as apparent from the foregoing disclosure, it is appreciated that, throughout the foregoing disclosure, discussions using terms such as “processing,” “computing,” “calculating,” “determining,” “displaying,” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.

One or more components may be referred to herein as “configured to,” “configurable to,” “operable/operative to,” “adapted/adaptable,” “able to,” “conformable/conformed to,” etc. Those skilled in the art will recognize that “configured to” can generally encompass active-state components and/or inactive-state components and/or standby-state components, unless context requires otherwise.

The terms “proximal” and “distal” are used herein with reference to a clinician manipulating the handle portion of the surgical instrument. The term “proximal” refers to the portion closest to the clinician and the term “distal” refers to the portion located away from the clinician. It will be further appreciated that, for convenience and clarity, spatial terms such as “vertical”, “horizontal”, “up”, and “down” may be used herein with respect to the drawings. However, surgical instruments are used in many orientations and positions, and these terms are not intended to be limiting and/or absolute. Those skilled in the art will recognize that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to claims containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.

In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms unless context dictates otherwise. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.”

With respect to the appended claims, those skilled in the art will appreciate that recited operations therein may generally be performed in any order. Also, although various operational flow diagrams are presented in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated, or may be performed concurrently. Examples of such alternate orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. Furthermore, terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.

It is worthy to note that any reference to “one aspect,” “an aspect,” “an exemplification,” “one exemplification,” and the like means that a particular feature, structure, or characteristic described in connection with the aspect is included in at least one aspect. Thus, appearances of the phrases “in one aspect,” “in an aspect,” “in an exemplification,” and “in one exemplification” in various places throughout the specification are not necessarily all referring to the same aspect. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more aspects.

Any patent application, patent, non-patent publication, or other disclosure material referred to in this specification and/or listed in any Application Data Sheet is incorporated by reference herein, to the extent that the incorporated materials is not inconsistent herewith. As such, and to the extent necessary, the disclosure as explicitly set forth herein supersedes any conflicting material incorporated herein by reference. Any material, or portion thereof, that is said to be incorporated by reference herein, but which conflicts with existing definitions, statements, or other disclosure material set forth herein will only be incorporated to the extent that no conflict arises between that incorporated material and the existing disclosure material.

In summary, numerous benefits have been described which result from employing the concepts described herein. The foregoing description of the one or more forms has been presented for purposes of illustration and description. It is not intended to be exhaustive or limiting to the precise form disclosed. Modifications or variations are possible in light of the above teachings. The one or more forms were chosen and described in order to illustrate principles and practical application to thereby enable one of ordinary skill in the art to utilize the various forms and with various modifications as are suited to the particular use contemplated.
